SPECIFICATION forming part of Letters Patent No. 392,5e6, dated November6, 1888.

(No model.)

To aZZ whom, it may concern:

Be it known that I, JACOB ENGEL, a citizen of the United States ofAmerica, residing at New Bedford, in the county of Ooshocton and Stateof Ohio, have invented certain new and useful Improvements inSelf-0losing Hatchways; and I do hereby declare the following to be afull, clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame, reference being had to the accompanying drawings, and to lettersor figures of reference marked thereon, which form a part of thisspecification.

My invention relates to certain new and use ful improvements indoor-operators for hatchways, the object of the same being to provide animproved means for opening and closing hatchway-doors of an elevatorshaft as the car is about to pass said door in either direction; and itconsists in providing the doors of the hatchway with geared segments,which engage with bell-crank segments having gear-teeth, said segmentsbeing connected to pivoted levers, which are operated to open and closethe hatchway-doors, the bottom portion of the cage engaging withthelevers on its downward movement, while the upper portion thereofengages with the under side of the doors on its upward movement, theparts being organized as shown.

My invention also consists in the construction and combination of theparts, as will be hereinafter fully set forth and specifically pointedout in the claims.

In the accompanying drawings, Figure 1 is a side view of my improvedautomatic closer for hatchway-doors. Fig. 2 is a sectional view takenthrough the line or x of Fig. 1. Fig. 3 is an edge view of the cagedetached.

A A refer to the uprights of the elevator, the inner edges thereof beingprovided with guides to a or projecting tongues, which lie within thegrooves 11, formed in the side pieces of the cage. These uprights aboveeach of the doors are provided with cut-away portions A, within whichthe doors will lie when swung upwardly to a vertical position, and theunder sides of the doors B B are each provided with strips a, which willform with the tongues a continuous guides for the cage.

the uprights A, and around said pins are placed coiled springs cl, oneend of which is made fast to the upright, the opposite end being securedto the bell-crank segment, so as to have a tendency to throw the outerend thereof downwardly and hold the doors normally closed. Instead ofemploying aspring in this connection the outer ends of the bell-cranksegments may be weighted, or weights may be attached to the rods, whichextend upwardly therefrom. I, however, prefer to employ the springs, asthey can be so adjusted as to ease the closing movement of thehatchway-doors. To the outer ends of the bell-crank segments D arepivotally secured rods E,the upperends of which are attached to theouter ends of bent levers F, which are pivotally attached to theuprights substantially on a line with the pivots of the bellcranksegments D. These levers F are of such alength that they extend beyondthe edges of the uprights, so that the cage will engage therewith on itsdownward movement, and when the ends of these levers are depressed,they, being connected to the segments hereinbefore described, willoperate the said segments to raise the doors and permit the passage ofthe cage through the hatchway.

The cage is provided with a curved bar, G, located to one side andattached to the main frame thereof, and the bottom of the platformadjacent to its corners is provided with rollers g g, secured insuitable bearings,which will contact with the long end of the lever.When the elevator is drawn upward, this curved bar G, attached to thecage, will contact with the under sides of the doors and open the same,and while the platform is level with the floor the ends of the leverswill bear against the sides of the aforesaid bar G, and as the cage ismoved upward the long ends of the levers will contact with the rollers,which will cause the levers to move slowly, so as to not close the doorwith undue jar.

I am aware that prior to myinvention ithas been proposed to provideself-closing hatchways with an arrangement of pivoted levers and weightsconnected to the doors, so that they will be opened and closed by thepassage of the cage or car, and I do not claim such construction,broadly; but

What I claim as new, and des re to secure by Letters Patent, is-

1. In an automatic hatchway-door operator, the combination, with thecasing and doors, of toothed segments secured to the hinge edge of thedoors, bell-crank levers pivoted to the easing and provided withsegmental racks meshing with the toothed segments, levers F, pivoted tothe casing above the bell-cranks with one end projecting into theelevatorshaft, and rods connecting said levers with the bellcranks,substantially as described.

2. The combination, with an elevator shaft and cage, of upwardly-openingdoors hinged in the shaft and provided on their hinge edges with toothedsectors, bell-crank levers pivoted to the shaft-casing and provided atone end with a segmental rack, springs secured to the casing and leversto move the levers in one direction, levers F, pivoted to the casingwith one end projecting into the shaft in the path of the cage, and rodsE, connecting the other ends of said levers with the bell-crank levers,substantially as described.

3. The combination, in a device for operating hatchway-doors, of asegment, 0, having gear-teeth, a bell-crank segment pivoted to theuprights, so as to engage with the segment 0, a spring, d, embracing itspivot, the ends being attached to said segment D and to the upright,connecting-rods E, and pivoted lever F, and the cage provided withrollers g and a bar, (1-, or angle-iron, the upper portion of which iscurved so as to contact with the under side of the hatchway-doors uponthe upward movement of the elevator, the parts being organizedsubstantially as shown, and for the purpose set forth.

In testimony whereof I affix my signature in presence of two witnesses.

JACOB ENGEL.
